Diffusion in fish gills
WebFish possess several gills located between their mouth cavity (buccal cavity). Gills of fishes consist of several gill arches on either side. From each gill arch extend two rows of gill filaments. Each filament is covered in lamellae. These further increase the surface area, and because they are thin, ensure that the diffusion distance between ... WebOct 28, 2015 · Fish gills use a design called ‘countercurrent oxygen exchange’ to maximize the amount of oxygen that their blood can pick up. They achieve this by maximizing the amount of time their blood is exposed to water that has a higher oxygen level, even as the blood takes on more oxygen. Countercurrent oxygen exchange (shown in the figure …

WebApr 1, 2024 · August Krogh made fundamental discoveries about both respiratory gas exchange and osmo/iono-regulation in fish gills. Dave Randall and co-workers identified a tradeoff between these two functions such that high functional surface area and low diffusion distance would favour O 2 uptake (e.g. exercise, hypoxia), whereas low …
WebAlveoli in the lungs, fish gills and the villi in the small intestine are adapted so that they have short diffusion distance, big concentration difference and large surface area. WebThe folded surfaces of the gills provide a large surface area to ensure that the fish gets sufficient oxygen. Diffusion is a process in which material travels from regions of high concentration to low concentration until …
Web1.2.4 The gills. The fish gill is a multifunctional organ involved in gas exchange, ionoregulation, osmoregulation, acid–base balance, ammonia excretion, hormone production, modification of circulating metabolites and immune defence (Rombough, 2007 ). In filter-feeding species, such as the sardine ( Sardina pilchardus ), the gills may also ... Air breathing fish can be divided into obligate air breathers and facultative air breathers. Obligate air breathers, such as the African lungfish, are obligated to breathe air periodically or they suffocate. Facultative air breathers, such as the catfish Hypostomus plecostomus, only breathe air if they need to and can otherwise rely on their gills for oxygen. Most air breathing fish are facultative air breathers that avoid the energetic cost of rising to the surface and the fitness cos…
